Poonkundran Department of Civil Engineering, Annamalai University, Chidambaram, 608002, Tamil Nadu, India DOI: 10.29322/IJSRP.9.07.2019.p9123 http://dx.doi.org/10.29322/IJSRP.9.07.2019.p9123 Abstract- The estimation of water quality is very important for Khalid Hameed Lateef 2011. Water quality index(WQI) is the human being knowing its suitability for quality analysis in and important tool to give the information on the water quality to the around Chidambaram Taluk. Water samples were collected from concerned citizens and policy makers. It is an important parameter 10 different areas of Chidambaram Taluk and analyzed various for the analysis and management of groundwater. WQI is defined characteristics of water samples. The results showed that many of as a rating reflecting the composite influence of different quality the water quality parameters from residential areas above the of water parameters Ramakrishnaiah et al., 2009. permissible limits of BIS and WHO. Index Terms- Water pollution, BIS, Water quality, Groundwater. II. MATERIAL AND METHODS All the water samples were collected from 2.5 litre clean and dry plastic canes without any air bubble. Then the water I. INTRODUCTION samples were analysed in the water analysis laboratory within roundwater is very important source of drinking water for four hours after sampling without mixing any preservatives. These G both human being and animal in the world. It is also very Water samples were collected in the month of April 2015 to month essential source of water for the drinking, agricultural and the of April 2016. The water samples temperature were noted in the industrial sector. Being a significant part of the hydrological cycle, sampling point itself. The samples were transfer to the laboratory water resources depends on the rainfall and recharge methods. to determine the major characterstics. The physical and chemical Groundwater quality is based on the physical, chemical and characterstics were analysed such as pH, turbidity, calcium, biological characteristics of groundwater. The suitability of magnesium, iron, fluoride, TDS, Total Hardness, chloride, groundwater for various uses majorly depends on quality of sodium, potassium, total coliform, using standard methods ISI, groundwater. Hence protecting the quality of groundwater is a 1983; Sing et al., 2008; Dhembare et al., 1998. Based on the major concern Packialakshmi et al., 2011. Water quality analysed data correlation co efficient was calculated by statistical assessment is the major important tool for share the information method. Water samples were collected and analyzed as per on the qualities of water to the public. It acts as the indicator of the procedures outlined in IS-2488/IS-3025/AWWA/ APHA. quality of water. The purpose of assessment water quality is to Sterilized containers were used for collection of water sample for turn multifaceted water quality data into simple information that bacteriological analysis, stored in ice-box and transported to the is essential for the public. Many other researchers have conducted lab for the analysis. The temperature is measured using the a study on groundwater quality by estimating the water quality thermometer and the pH is measured using the pH meter. The total index to substantiate the variation of groundwater quality Kumar dissolved solids are measured by Gravimetric method. Turbidity et al., 2013. is measured using an instrument known as nephelometer Hussain The availability of a water supply depends upon the both and Hussain 2004; Shah et al., 2005;APHA 1989. Atomic quality and quantity is vital to human existence. The supply for Absorption Spectrophotometry provides accurate quantitative water has increased over the year by year and this has led to water analyses for metals in waters. Total suspended solids are measured scarcity in many other part of the world. The situation is using Gooch Crucible and Total Hardness is measured using aggravated by the problem of contamination or water pollution. Titrimetric (EDTA) method Shyamala et al., 2008; Packialakshmi India is facing towards a freshwater crisis mainly due to improper et al., 2010; Kumar, 1997; Purandara et al., 2003. Sodium, miss management of water resources and environmental potassium by flame photometer and aluminium, manganese by degradation. This leads to deficiency of access to safe drinking atomic absorption spectrophotometer method Agbaire et al., 2009; water supply to millions of people. This drinking water crisis is Palanisamy et al., 2007. already evident in many parts of India, varying in scale and intensity depending mainly on the time of the year Sundara Kumar et al., 2010. III.
